Paragraph 2 Data within possession or power
United Kingdom
A relevant data-holder is not required by regulations under paragraph 1 to provide data to HMRC unless the data are within their possession or power.
The Treasury may by regulations make provision requiring a relevant-data holder to make reasonable efforts to obtain any specified identifying information that the relevant data-holder would, but for sub-paragraph (1), be required to provide to HMRC.
In this Schedule “identifying information” means any information which identifies a person or an account including, in particular, a company’s registered number, a national insurance number, a unique taxpayer reference, a VAT registration number or any other unique government-issued identifier associated with a person or account.
